Minecraft cake block cake

If items in the computer game Minecraft were translated to real life size, the cake block would be about 3 feet square. This one was only a 9 inch square but challenge enough! My son does not like fondant, and really wanted the different parts & colors to be flush, as they are in the game (and not have the white frosting 'sticking out' on top of the brown). So this is all buttercream (inset red squares are modeling chocolate), with the pattern on the sides piped on. Texture on the lower half is cinnamon pressed into the buttercream.
